Be it known that I, PETER G. JAcoBsoN, a citizen of the United States, residing at Chicago, -in the county of Cook and the State of Illinois, have invented a certain- 0n line 8-8 of Fig. 4; Fig. 9 is a perspecnew and useful Improvement in Die Mechative view illustrating one of the condenser msm, of which the following is a full, clear, plate supports and a condenser plate in concise, and exact description. A separated relation; Fig. 1() is a perspective My invention relates to die mechanism view illustrating one of the condenser supand is of particular service in effecting the ports and a condenser plate after assembly, one condenser plate being omitted from one densers with complemental condenser arts. The die mechanism of myinvention inc udes a group ofdie plates having narrow spaces therebetween in which the condenser` plates of a group constituting a condenser side may be partially received preparatory to the die operation. There is another group of die plates complemental to the first and in register therewith, this second group of die plates being moved against the first in the condenser plate assembling operation. Metallic supports are provided for the condenser plates, these supports being slotted to receive the condenser plates, the plate receiving slots being slightly wider than the thickest plate that is apt to be included in the condenser construction. The die plates are desirably formed to swedge the metal of the condenser plate supports between the slots therein so as to contract the width of portions of these slots to hold the condenser plates firmly in assembly with their Asupports. The swedging effected by the die mechanism produces enlargements, in the metal between the condenser plate receiving' slots, that are symmetrical whereby the median planes of the condenser platesare caused to be equidistant irrespective of the thickness of the condenser plates which varies in practice.

The invention will be more fully lexlained in connection with the accompanyving' drawing in which Fig. 1 is a plan view of my improved die mechanism; Fig. 2 is a sectional View on line 2-2 of Fig. 1; Fig. 3 is. a view somewhat similar to Fig. 2 but showing the two dies in separated relation and a'condenser side between the two dies and in the act of being placed in the lower die; Fig. 4 is a sectional View illustrating the lower die with a condenser side held thereby in readiness to be operated upon; Fig. .5 is a sectional view on line 5-5 of Fig. 3 vbut with the condenser side `in place within the lower die; Fig. 6 is a view simi- 11 is a View illustrating on` a larger scale parts of the dies in readiness to complete the assembly of the condenser plates and their support; Fig. 12 is a view similar to Fig. 11 but illustrating the completion of the die operation; Fig. 13 is a sectional view on line 13-13 of Fig. 14; and Fig. 14 is a sectional view on line 14-14 of Fig. 12.

The die mechanism of my invention is^ particularly adapted to the assembly of the condenser plates of stator condenser sides with the supports for such plates. The stator condenser side illustrated includes a be assembled with metallic supportsv 2. These supports are preferably tubular or sleevelike and are initially of U shape as illustrated in Fig. 9. The sides of each supcate with the interior of the support to form spaced apart fingers 4. The condenser plates, which are preferably triangular in the lingers 4 are curled to finally form a slotted sleeve support as illustrated in Fig. l0 where the tips of the. fingers are shown Das being spread symmetrically in Aorder to lirmly engage the condenser plates and hold the median planes thereof equidistant.

The lower set of die plates 5 are held in upright position upon the base 6, The Adie plates may' be integrally formed with a connecting member 7. The condenser plates are preliminarily held on the pins 9 carried on a mounting 10 which is moved, together with the pins, transversely of the die plates to enable said .pins fto enter the interiors of the condenser plate su orts 2. The supporting block is carrie y a cross-head 11 which has pin and slot connection` 13 with block 10 thereon may be moved transversely of the die plates so as to enter .the pins 9 into the condenserplate supports -2prepara- -7 of Fig. 4; Fig.8 is a sectional view of the slots to reveal the construction; Fig.,

port are formed with slots 3 that communi-' shape, are placed in the slots, 3 whereafter a lever 13 whereby said cross-head and the' number of condenser plates 1 which-are to aan' tory to the assembling operation and to withdraw these pins after the assembling operation to permit the removal of the completed condenser side. The pins 9 are not only passed through the supports 2 but they are also passed through openings 14 in the block 15 and the openings 16 in the block 17, the latter block being movable transversely of the die plates, these blocks 15 and 17 being placed in engagement with the ends of the condenser plate supports2 to further dene the position of the condenser side being operated upon. The die plates are held inassembly withl theblock by means of the bolts 5 The block 15 may be heldin fixed relation with the baseH 6 by the bolts 18. An eccentric 19l is received within and engages the sides of the slot 20 in the base extension of theblock 17. This eccentric has a handle 21 by which it may be turned upon its shaft 22 to ,place the I block 7 against the adjacent ends of the condenser plate supports 2 to prepare for the die operation, and to withdraw the block 17 from said, supports 2 uplon the completion of the die operation. T e openings' 14 and 16 are vertically elongatedthe pins 9 being forced against the upper sides of these openings by means of -upright coiled springs 23 that are parallel with the die plates and which are 'bottomed upon the shelf 24 provided upon the cross-head 11 and whose upper ends are received in sockets formed in the bottom of the block 10, this -block being adapted to slide vertically upon said l cross-head. The springs 23,cause the condenser side belng operated upon 'to'be initially held inthe upper positlon illustrated ziov -in Fig. 5. The condenser plate support 29 is placedto have its lingers extend down-v wardly toward the arcuate concave anvils 25 formed inthe tops of the die plates 5, while the outer and lower supports -2 are placed to have the lingers thereof extend verticallyv upward. Unslotted portions of these sup- 4ports face the 'concave seat-,S126 lin said die plates.-

The uppegl` set of die A lates .27 depend from a common base 28 t at may be intev,27 is movedV downwardly into close grally formed' therewith,.this base being so assembled with the vertically movable carrier 29A that the die plates 27 are in exact register with the die plates 5. When the condenser side to be operated upon is'positloned as described and as illustrated in Fig. 5, the upper lset o upright die plates roximity to the plates 5 as illustrated in Fig. 6.

In this movement the die plates 27 are engaged with portions of the condenser plate supports 2 that are between the condenserlates and ress these supports into 4assemly with t e condenser plates. In this downward movement,'the anvils 25 curl the lingers of the central' and uppermost condenser plate support 2 to form'this support into a tube whose bore is defined by the uppermost and central pin 9 The upwardly extending fingers of the remaining condenser plate supports are similarly curled by the concave arcuate lanvils v formed in the bottoms of and near the ends of the die ,plates 27. The anvils desirably have the con- Vex cross sectional formation, illustrated in Figs. 12 and 14 so that the. lingers of the condenser plate supports 2 are not onlycurled as described 4but are also swedged at their tips and symmetrically, whereby Athe ing'er tips are spread into tight-holding engagement with the condenser plates and in a manner to hold the medianplanes of these plates equidistant. The block 10 is depressed as the curling-'and swedgin opera- .tion'is in process by-means of the a justable lposts 31 dependlng from the carrier 29 so with their supports has been completed, the' lever 13 Ais moved to withdraw the crosshead 11, together with the block 10 and the pins 9. The 'handle 21 is also operated to- Withdraw the block 17. The upper set of die plates being withdrawn, the completely assembled condenser side may be dislodged from the lower set of die plates. -`To this end, ejecting ngers or blades are placed between the bases ofthe die plates 5 and are upwardly moved :to eject the completed condenser side. The fingers 32 may be hinged, eachJ at one end, and may be provided at their other ends with a common handle 33 whereby the ejecting fingers may be swung upwardly to eject thel completed condenser side and downwardly, prepara` tory to the location of a new condenser side; Thebores which aredened .by the pins 9 in the supports 2 are vgenerally penetrated by means of assembling bolts which are em- -ployedto mount the condenser side in a stationary position. The complemental con-- denser Vside is not illustrated. It is custom'- Varilyrotatively mounted as is well understood in order to adjust the condense:` capacity.
